To all whom it may concern:

Bo it'kfnown that we, GEORGE H. FISHER 'and Pm J. ONEIL, c tizens of the United States, residing at Leavenworth, in the county of Leavenworth and 'State of Ram sas, have invented certain new and useful Improvements in A"paratu'sfor Making .Artificialclce, of which-the following is a specification.

Ourinvention relates to the manufacture Of:8.1ll1fi01 8.l ice from raw water, i. 0. water a: which has not been distilled, and our objects are to provide an improved apparatus whereby the raw water may be frozen under such conditions as will result in the forma 'tion of crystal ice free from impurities.

Our invention has for one of its objects,-

the elimination from the ice of the 0bjec-. tionable features above enumerated.

By ersonall conducted experiments we have discovere that the foregoing object can be. economically and successfully attained by agitating through means of waterjets, the raw water during the freezing process, and our invention relates more particularly to the agitation and circulation b water-jets of the raw water to be congeale and the manner in whichsaid water-jetsare produced, applied, and governed.

The simplicity, construction, and opera-- tion of our invention is such that it cambe readil' applied to ice making plants now -installe on'tll'e distilled water principle, without discarding any part of said plants, .it

being only necessary to discontinue the use of the distilling-apparatus when making ice from raw water. N o'special refri erant, or

special size or design of .congea ing-cans, brineianks, h'oists or applianccsmther than those now in general use willgbe in the application of our invention to existare supporteding distilledwater ice pl'an ts. Therefore any establ shed distilled -iv ier*="1fe -p1a'm7 may be equipped with oiir irii 'efntioii, so that we may be produced either, frornf raw 'i'water or distilled water, as desired' 'f' -Referring to the.accompanying dr awings which show the ,prefer fed forin 'ofZipperratus' for carrying; out our invention:

Congealing-cans 1 :are of the'custom- 'ary construction except that each has a central depresslon 1, iniits' botto'nr portion" to center a downwardly tapering jet-tube 2, havmgportsB, at its lowerend' J et-tubes 2, extend upward through the congealingcans D and through centrall openi'ngs t in covers (:1, and their upper o en terminals communicate each with a-;ho low coupling 5. Covers, C are provided with- 'piybtallymounted lids c, adapted to lnb1faCtl1bS 2 I and close the openings 4,. 5 are 'swiveled in' series upbria' plurality" of -p p to I municate' witl gs a idcoiipjing's when the same occupy their normalior hbri'zqntalpo'sitions, as shownin Eig)s. 1-andf:2,f Biahch-pipes 6,

a pl ral ty '1sIfand' Branc Geomrnuniiiate Wlth-d lmader 8 containing fluid (preferabl compressed air) under pressure. ;Qn,e .,en o'f jheader 8 COIHFnunicates, p ie fn-iwi h. ai -W pressor; and its opposite en' ci .-is proii'ded with a reliefwalve 9,o'perably -.ec d theree 10. Valyefi free'end-wlth astem ll weight 12, adjustably-mounted thereon to assist in closing the valve after the same has been ened. A set-screw 13, 1S provided to loc tlie counterweight 12 at any of its adjusted positions upon stem 11.

14 designates a cam adapted to impinge against stem 11, and thus open valve fi. Cam 14.- is fixed to a shaft 15, provided with a pulley 16, driven by a belt- 17, leading from any suitable motor.

In racticethe congealing-cans are lowered into the brine-tank A and filled to the'proper level with raw water. Covers O are placed in position and the ettubes 2 are passed through openings 4: until their lower terminals rest. in depressions 1. Openings 4: are then closed by lids c, and 'cou lings 5 are lowered into engagement witi the upper open ends-0t the et-tubes. As the jet-tubes are-inserted in the cqngealin cans D, the water will enter said Jet tu es through ports 3. to a level .with the surrounding water in the cans. Then when the necessary maximum air-pressure is established in the header 8, branch pipes 6, couplings 5 and jet-tubes 2, a certa n amount, say, nine-tenths of the water. in

the jet-tubeswill be foroed back into the can. I

Pressure is then reduced to low or no pres- .sure by cam 14 engaging stem 11, azidopening valve 9 to permit the compressed air or a portion thereof in header 8 to exhaust therefrom When the pressure 18 thus reduced the counteracting force of gravity will again force water into the interior of the jetstubes through ports 8, to a. level with the surroun water in the congealmg cans D. There ore, an alternating h gh and low, or no pressure, is obtained, which acts like a piston in alternately forcing water from the jet-tubes 2 and permitting it to reenter said tub'es. 'ihJS alternating in and 'out flow of water in the jet-tubes, agitates and circulates the surroun water in the romot-mg t e escape of co g l :Erb ga air-bu b es. and other undesirable elements --:Erom the,water during the recess of andresulting in the pr uction f crystal ice. TIie-jet-tubes 2, may be removed a's soon as proceeded farenou h for the ice to contact with said tubes, an the resultant holes filled with water which ermitted to freeze, 9r gaid jet-tubes may allowed'to remain until .the ice freezes solidl around the same and't-hen be withdrawn after the ice-block have been removed from the congeali ngcans, lea .holes thro h the centers of the mabigavailable or the introduction .of a bar, or other tool to facilitate handling .the ice-blocks, When the jettubes 2 and the congealing-can" D, are to be removed, couplings 5 are swung upward' to a vertical position, so that they will be nectmg sai the process of freezing has out of the way, and also cut oil the flow of fluid throu h ports 7.

Having t us described our invention what we claim, and desire to secure by Letters Patent is:
